`JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 418,123, dated December24, 1889.

Application led April 25, 1889.

T alt whom it may concern:

Be it known that I, PAUL H. GRIMM, of Glen Cove, in the county of Queensand State of New York, have invented a certain new and usefulImprovement in Journal Boxes, of

which. the following is a specification.

My improvement relates to journal-boxes which are kept cool by a currentof water.

I will describe in detail a journal-box emio bodying my improvement, andthen'point out its novel features in a claim.

In the accompanying drawings, Figure l is an elevation, partly inlongitudinal section, of a journal-box embodying my improvei 5 ment.Fig. 2 is a vertical transverse section taken on the line 5c Fig. 1*,and showing portions of certain supports for the journalboxes,

Similar letters of reference designate corre- 2o sponding parts in boththe figures.

A designates a portion of a shaft.

B B designate a journal-box. The portion B of the journal-box iscylindrical, and constitutes, in effect, a bushing, in which the shaft Amay rotate. The portion B entirely surrounds the portion B, and its endsare provided with inwardly-extending flanges d. Vhen the parts B B aretogether, there will be an annular space C between the por- 3o tion B'and the portion B and entirely sur rounding the latter. In assemblingthe parts the portion B is preferably driven in friction-tight into theportion B', the diameter of the spaces between the flanges a of the 55portion B being just sufficient to admit of this. By this means awatertight joint is formed between the flanges a and the portion B. Theportion B constitutes,in effect, a casing for the portion B. Water forcool- 4o ing the j ournal-box circulates entirely around the portion Bthrough the annular space O, so that the shaft A will be entirelysurrounded by cooling-water. Vater is introduced into the space Othrough a pipe D,

provided with a stop-cock d. The pipe D has a screw-threaded connection,as shown, with the portion B of the box. The water,

after having circulated through the annular Serial No. 308,594. (Nomodel.)

space O, is discharged through a pipe E, provided with a stop-cock e.The pipe E also 5o has a screw-threaded connection with the portion B ofthe journal-box.

F designates a nozzle having a screwthreaded aperture f near its upperend adapted to receive a grease-cup. The nozzle F is provided with ashank f', which shank, as here shown, extends loosely through asuitably-formed aperture in the portion B of the journal-box. The shankpasses wholly through the annular space C, and has a 6o screw-threadedengagement with the portion B of the journal-box. It is providedcentrally with a passage f2, the open end of which is adjacent to theshaft A. 'Ihrough this passage grease to lubricate the shaft will pass.I have shown the portion B as provided with an annular neck g, extendingabout the opening therein, through 'which the shank f passes, and I haveshown the nozzle F as provided with a shoulder g. 7o Between theshoulder g and the neck g isa washer g2, whereby when the nozzle Fissecured in position a water-tight joint will be formed between it andthe portion B. Water from the annular space C cannot therefore It willbe seen that by my improvement not only do I cause Water to circulateen- Se tirely around the shaft', but also that the nozzle F is whollyclosed to the admission of water, so that there can be no admixture ofwater with the grease being supplied to the shaft. The construction,furthermore, is simple, few parts being employed, and there is littleliability of the journal-box getting out of order. V

What I claim as my invention, and desire to secure by Letters Patent,is-e The combination,with a shaft A, of a journalboX comprising acylindrical bushing B, and an external cylindrical casing B', madeindependent of the bushing B, between which and the bushing B is anannular space C, an inletpipe D for water communicating with saidannular space, an outletpipe El for Water also eommunioating with saidannulai` space, and a nozzle F, extending through the portions B B andthe annular space C and engaging the bushing B, said nozzle beingprovided with a passagefor grease to be supplied to the shaft, whichpassage is Wholly closed to lche admission of Waterfiorn the annularspace C, substantially as specified.
